CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to Korean patent application number 10-2013-0108569 filed on Sep. 10, 2013, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated by reference herein.

BACKGROUND

1. Technical Field

Various embodiments of the present invention relate to an electronic device, and more particularly, to a data storing system and an operating method of a data storing system.

2. Related Art

A semiconductor memory device among data storing devices may be generally classified as either a volatile memory device or a nonvolatile memory device.

The volatile memory device may perform a read/write operation at a high speed, but may lose stored data when a power supply is blocked. Meanwhile, the ion-volatile memory device has a relatively low rite and read operation speed, but may retain the stored data even when not powered. Accordingly, the non-volatile memory device is used to store data to be maintained regardless of the power supply. The non-volatile memory device includes a read only memory (ROM), a mask ROM (MROM), a programmable ROM (PROM), an electrically programmable ROM (EPROM), an electrically erasable and programmable ROM (EEPROM), a flash memory, a Phase-change random access memory (PRAM), a magnetic RAM (MRAM), a resistive RAM (RRAM), a ferroelectric RAM (FRAM), and the like. Flash memories may be divided into a NOR type and a NAND type.

The flash memory has an advantage of the RAM in which data is freely programmed and erased, and an advantage of the ROM in that stored data is maintained even when not powered. The flash memory is widely used as a storage medium of a portable electronic device, such as a digital camera, a personal digital assistant (PDA), and an MP3 player.

It is required for a semiconductor memory device, including the flash memory, to have high data reliability and yield.

DETAILED DESCRIPTION

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings in detail. However, the present invention is not limited to an embodiment disclosed below and may be implemented in various forms and the scope of the present invention is not limited to the following embodiments. Rather, the embodiment is provided to more sincerely and fully disclose the present invention and to completely transfer the spirit of the present invention to those skilled in the art to which the present invention pertains and the scope of the present invention should be understood by the claims of the present invention. Throughout the disclosure, reference numerals correspond directly to the like numbered parts in the various figures and embodiments of the present invention. It is also noted that in this specification, “connected/coupled” refers to one component not only directly coupling another component but also indirectly coupling another component through an intermediate component. In addition, a singular form may include a plural form as long as it is not specifically mentioned in a sentence.

FIG. 1 is a block diagram illustrating a data storing system according to an embodiment of the present invention.

Referring to FIG. 1, a data storing system 100 may include a semiconductor device 110, and a controller 120 for controlling an operation of the semiconductor device 110 in response to a request of a host.

The semiconductor device 110 performs a program operation and a read operation, or an erase operation in response to a command CMD and an address ADD input from the controller 120. The semiconductor device 110 performs a test operation on a read fail block among memory blocks in response to the command CMD and the address ADD input from the controller 120.

The controller 120 may include a bad block management module 122 storing a read fail block address and a bad block address. When the program operation or the erase operation on the memory block is determined to be failed, the controller 120 stores an address corresponding to the memory block in the bad block management module 122 as a bad block address. When the read operation on the memory block is determined to be failed, the controller 120 stores an address corresponding to the memory block in the bad block management module 122 as a read fail block address. When the test operation on the memory block is determined to be passed, the controller 120 deletes (or excludes) the read fail block address from the bad block management module 122, and when the test operation is determined to be failed, the controller 120 changes the read fail block address to a bad block address, and stores the bad block address in the bad block management module 122.

The semiconductor device 110 performs the erase operation on the read fail block in response to an erase command during the test operation. The controller 120 changes the read fail block address to a bad block address when a pass/fail signal P/FS1 denotes that the erase operation is determined to be failed, and stores the bad block address in the bad block management module 122.

When the erase operation is determined to be passed, the semiconductor device 110 performs a program operation of programming data with a predetermined pattern in memory cells of the erased read fail block in response to a program command. The controller 120 changes the read fail block address to a bad block address when the pass/fail signal P/FS1 denotes that the program operation is determined to be failed, and stores the bad block address in the bad block management module 122.

When the program operation is determined to be passed, the semiconductor device 110 performs the read operation of reading data from the memory cells in response to a read command. Based on the read data, when the read operation is determined to be passed, the controller 120 deletes (or excludes) the read fail block address from the bad block management module 122, and when the read operation is determined to be failed, the controller 120 changes the read fail block address to a bad block address, and stores the bad block address in the bad block management module 122.

As an exemplary embodiment, the controller 120 may output the command CMD and the address ADD to the semiconductor device 110 to perform the test operation during an idle period of the data storing system 100. Accordingly, it may be possible to prevent the data storing system 100 from performance deterioration due to additional performance of the test operation.

As an exemplary embodiment, the controller 120 may output the command CMD and the address ADD to the semiconductor device 110 to perform the test operation when a free (or available) address storage space within the bad block management module 122 becomes equal to or lower than a threshold. Accordingly, it may be possible to prevent the performance of the test operation from being stopped due to a small free space of the address storing space of the bad block management module 122, and continuously perform the test operation.

As an exemplary embodiment, the semiconductor device 110 stores the read fail block address and the bad block address stored in the bad block management module 122. The controller 120 outputs the command CMD and the address ADD so that the read fail block address and the bad block address stored in the semiconductor device 110 are stored in the bad block management module 122 when power is on. Accordingly, even though the power is off the read fail block address and the bad block address may be stably maintained. Further, the bad block management module 122 may not need to include a non-volatile storing means, and includes a volatile storing means, thereby improving an operation speed.

FIG. 2 is a block diagram for describing the bad block management module illustrated in FIG. 1.

Referring to FIG. 2, the bad block management module 122 may include an address storing unit 124 and an error correction unit 126.

The error correction unit 126 detects and corrects an error of data DATA read from the semiconductor device, and generates the pass/fail signal P/FS2 for the read operation depending on the error detection.

The address storing unit 124 stores and changes the read fail block address corresponding to the memory block of which the read operation is determined to be failed, and the bad block address corresponding to the memory block of which the program operation or the erase operation is determined to be failed. The address storing unit 124 may include a bad block list (or a bad block table) for storing and changing the read fail block address and the bad block address.

During the test operation, the address storing unit 124 changes the read fail block address to the bad block address when the pass/fail signal P/FS1 denotes that the program operation or the erase operation is determined to be failed, and stores the changed bad block address in the bad block list. During the test operation, the address storing unit 124 excludes the read fail block address from the bad block list when the pass/fail signal P/FS2 denotes that the read operation is determined to be passed, and changes the read fail block address to the bad block address when the pass/fail signal P/FS2 denotes that the read operation is determined to be failed, and stores the changed bad block address in the bad block list. For reference, the address storing unit 124 may include a volatile memory such as an SRAM.

Accordingly, when the memory block on which the read operation is determined to be failed the test operation is performed, and the memory block is determined as the bad block or is not determined as the bad block based on a result of the test operation, so that reliability and yield of the device may be improved.

FIG. 3 is a diagram for describing the bad block list included in the address storing unit 124 illustrated in FIG. 2.

Referring to FIG. 3, the bad block list may include block numbers (or block addresses) and marks. Bad block addresses and read fail block addresses are stored (or written) in the bad block list. When the program operation or the erase operation on the memory block is determined to be failed, an address corresponding to the memory block (i.e., the bad block address) is stored in the bad block list, and marked as “X”. When the read operation on the memory block is determined to be failed, an address corresponding to the memory block (i.e., the read fail block address) is stored in the bad block list, and marked as “O”. That is, in the bad block list, the bad block address and the read fail block address are divided by the marks.

For example, memory blocks 1, 3, and Q are stored in the bad block list as the read fail block, and memory block 2 is stored as the bad block in the bad block list. It is determined whether the provisional read fail block is the bad block or a good block by performing the aforementioned test operation.

FIG. 4 is a block diagram illustrating the semiconductor device illustrated in FIG. 1.

Referring to FIG. 4, the semiconductor device may include a memory array 210 including a first to m^(th) blocks MB1 to MBm, and a peripheral circuit PERI performing a program operation, a read operation, and an erase operation on memory cells included in a selected page of the memory blocks MB1 to MBm. The peripheral circuit PERI may include a control circuit 220, a voltage supply circuit 230, a page buffer group 240, a column circuit 250, an input/output circuit 260, and a pass/fail check circuit 270.

The memory cells included in the memory block may be divided in the unit of a physical page or a logical page. The page serves as a basic unit of the program operation or the read operation.

The control circuit 220 outputs a voltage control signal VCON for generating a necessary voltage to perform the program operation, the read operation or the erase operation in response to a command CMD input through the input/output circuit 260 from the outside, and outputs a PB control signal PBCON for controlling page buffers PB1 to PBk included in the page buffer group 240 according to the type of operation. Further, the control circuit 220 outputs a row address signal RADD and a column address signal CADD in response to an address signal ADD input from the outside through the input/output circuit 260.

The voltage supply circuit 230 supplies operating voltages necessary for the program operation, the read operation, and the erase operation on the memory cells to local lines in response to the voltage control signal VCON of the control circuit 220. The voltage supply unit 230 may include a voltage generating circuit and a row decoder.

The voltage generating circuit outputs operating voltages necessary for the program operation, the read operation, and the erase operation on the memory cells to global lines in response to the voltage control signal VCON of the control circuit 220.

The row decoder connects the global lines and the local lines so that the operating voltages output from the voltage generating circuit to the global lines is transmittable to the local lines of the memory block selected in the memory array 210 in response to the row address signals RADD of the control circuit 220.

The page buffer group 240 includes the page buffers PB1 to PBk connected with the memory array 210 through bit lines BL1 to BLk. The page buffers PB1 to PBk of the page buffer group 240 selectively precharges the bit lines BL1 to BLk depending on input data to store data in the memory cells, or senses voltages of the bit lines BL1 to BLk to read data from the memory cells in response to the PB control signal PBCON of the control circuit 220.

The column circuit 250 selects the page buffers PB1 to PBk included in the page buffer group 140 in response to the column address signal CADD output from the control circuit 220. That is the column circuit 250 sequentially transmits the data to be stored in the memory cells to the page buffers PB1 to PBk in response to the column address signal CADD. Further, the column circuit 250 sequentially selects the page buffers PB1 to PBk in response to the column address signal CADD so that the data of the memory cells latched in the page buffers PB1 to PBk by the read operation is output to the outside.

In order to store data in the memory cells during the program operation, the input/output circuit 260 transmits the data to the column circuit 250 under the control of the control circuit 220 to input the data input from the outside to the page buffer group 240. When the column circuit 250 transmits the data transmitted from the input/output circuit 260 to the page buffers PB1 to PBk of the page buffer group 240, the page buffers PB1 to PBk store the input data in internal latch circuits. Further, the input/output circuit 260 outputs the data transmitted through the column circuit 250 from the page buffers PB1 to PBk of the page buffer group 240 to the outside.

The pass/fail check circuit 270 outputs the pass/fail signal P/FS1 in response to comparison result signals output from the page buffers PB1 to PBk, respectively, in a program verification operation performed after the program operation or an erase verification operation performed after the erase operation. Particularly, a threshold voltage of the memory cell is compared with a target voltage in the program verification operation or the erase verification operation, and a result value of the comparison is latched in the internal latch circuits of the page buffers PB1 to PBk. Further, the latched comparison result signals are output to the pass/fail check circuit 270. The pass/fail check circuit 270 outputs the pass/fail signal P/FS1 representing whether the program operation or the erase operation is completed to the control circuit 220 in response to the comparison result signals. The pass/fail signal P/FS1 is output to a controller through the input/output circuit 260.

FIG. 5 is a flowchart for describing a method of storing a bad block address according to the exemplary embodiment of the present invention.

Referring to FIGS. 1, 2, 3, and 5, in the method of storing a bad block address, a command is first received from the controller (S310).

When the received command is a program command or an erase command, a program operation or an erase operation is performed on a memory block (S320).

Next, a program verification operation or an erase verification operation is performed (S330).

When the program operation or the erase operation is determined to be failed as a result of the performance of the program verification operation or the erase verification operation, an address corresponding to the memory block is stored in the address storing unit 124 of the bad block management module 122 as a bad block address (S340).

Meanwhile, when the received command is a read command, a read operation is performed on the memory block (S350).

The error correction unit of the controller performs an error correction operation based on the read data (S360). When the read operation is determined to be failed, for example, when the number of error bits of the data is larger than the number of error correctable bits, the address corresponding to the memory block is stored as a read fail block address in the address storing unit 124 of the bad block management module 122 (S370).

When the program operation, the erase operation, or the read operation is determined to be passed, the process returns to the step S310.

FIG. 6 is a detailed flowchart for describing a step S370 illustrated in FIG. 5.

Referring to FIGS. 3 and 6, the had block address and the read fail block address may be stored in the bad block list.

When an address corresponding to a memory block on which a read operation is determined to be failed, contrary to the had block address, a read fail mark may be added to the read fail block address (S380). That is, the fail block address may be assumed as a provisional bad block address.

Next, the corresponding block address is stored in the bad block list as the fail block address (S390).

FIG. 7 is a flowchart for describing a method of updating the bad block address according to the embodiment of the present invention.

Referring to FIG. 7, the bad block list is first scanned (S410).

Whether the memory block is a read fail block is checked (S420), and a test operation is performed on the read fail block (S430). When the memory block is checked and determined that it is not a read fail block, the bad block list is continuously scanned.

A result of the performance of the test operation is checked (S440), and when the test operation is determined to be passed, the read fail block address is deleted (or excluded) in the bad block list (S450). When the test operation is determined to be failed, the read fail block address is changed (or determined) to the bad block address (S460).

Accordingly, when the memory block on which the read operation is determined to be failed, the test operation is performed, and the memory block is determined as the bad block or as a good block based on a result of the test operation, so that reliability and yield of the device may be improved.

FIG. 8 is a flowchart for describing additional steps for the method of updating the bad block address illustrated in FIG. 7.

Referring to FIG. 8, before scanning the bad block list (S410), whether the data storing system is currently operated in an idle period may be first checked (S402).

When the data storing system is operated in the idle period, the bad block list is scanned (S410). When the data storing system is currently not operated in the idle period, the scanning of the bad block list is waited, for example, for a predetermined interval (S404). Accordingly, it may be possible to prevent the data storing system from performance deterioration by additionally performing the test operation. Accordingly, it may be possible to prevent the data storing system 100 from performance deterioration due to additional performance of the test operation.

FIG. 9 is a detailed flowchart for describing the step S430 illustrated in FIG. 7.

Referring to FIG. 9, when the memory block is checked as a read fail block at the step S420, an erase operation is performed on the memory block (i.e., the read fail block), on which the test operation is to be performed, when performing the test operation (S431).

A result of the erase operation is checked (S432), and when the erase operation is determined to be passed, a program operation of programming data with a predetermined pattern in memory cells of the read fail block is performed (S433). When the erase operation is determined to be failed, the read fail block is determined as the bad block (S460).

Next, a result of the program operation is checked (S434) and when the program operation is determined to be passed, a read operation of reading the data with the specific pattern from the memory cells is performed (S435). When the program operation is determined to be failed, the read fail block is determined as the bad block (S460).

Then, a result of the read operation may be checked (S440). When the read operation is determined to be passed, the read fail block is not determined as the bad block, that is, the read fail block is determined as a good block (S450). When the read operation is determined to be failed, the read fail block is determined as the bad block (S460).
